Black's classification of carious lesions:
Class I - Restorations of the occlusal surface of premolar and molars or lingual surface of anterior teeth
Class II - Restorations of the proximal surfaces of posterior teeth
Class III - Restorations of the proximal surfaces of anterior teeth without incisal edge involvement
Class IV - Restorations of proximal surfaces of anterior teeth with incisal edge involvement
Class V - Restorations of the cervical margin
Indications:
Cervical carious lesion
Abrasion
Abfraction
Discoloured dentition anteriorly
Procedural steps:
Preoperative
Select enamel and dentine composite shade utilising Vita guides under natural light prior to commencing the procedure
Administer local anaesthetic for deep carious lesions or patient discomfort expected
Isolate tooth using cervical retraction providing clamps and rubber dam, however, if incomplete visualisation of lesion, consider continual aspiration without isolation.
Caries removal
Access carious lesion with tungsten carbide bur, ensuring to avoid gingival damage
Remove peripheral infected dentine with excavator or carbide rose head bur
Remove deep infected dentine +/- affected dentine in anterior dentition with excavator, especially if in close proximity to the pulp
Consider air abrasion for removal of staining in the event of a tooth wear lesion
